Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If complex connections and multiple components are used in the conveyor frame, then structural integrity is improved, but cleanability deteriorates due to crevices and difficult-to-clean areas

Engineering Contradiction:
Improvestructural integrityVSAvoidcleanability
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The patent merges multiple components (frame members, support structures, and reversing elements) into a unitary integrated frame structure. This consolidation eliminates the crevices and gaps that exist between separate components, making the entire conveyor system cleanable as a single continuous surface while maintaining structural strength through the integrated design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent employs curved surfaces and rounded transitions throughout the frame structure, particularly at corners and joints. These curved geometries eliminate sharp angles and crevices where debris could accumulate, creating smooth surfaces that are easily cleanable while preserving the structural integrity of the frame through optimized curvature radii.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Strength

If multiple components and complex connections are used, then structural support is improved, but device complexity increases making cleaning problematic

Engineering Contradiction:
Improvestructural supportVSAvoidnumber of components
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent combines multiple previously separate components into a single integrated frame structure. The unitary design integrates frame members, support elements, and belt reversing mechanisms into one cohesive structure, reducing the total number of components while maintaining all necessary structural support functions.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If integrated rails with curved ends are used, then cleanability is improved by eliminating crevices, but manufacturing complexity may increase

Engineering Contradiction:
ImprovecleanabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent utilizes curved ends on the longitudinal rails to form the belt reversing elements. These curved geometries eliminate sharp corners and crevices, creating smooth continuous surfaces that are easily cleanable. The curvature is designed to be manufacturable using standard forming processes while achieving the cleanability objective.

Inventive Principle:
Principle #14Spheroidality (Curvature)
